Keep in mind!

Much has changed since your last system purchase! There are 2 stage furnaces, 2 stage compressors, variable speed blowers, modulating valves, seer ratings from 13-21. AND Lots of "bells and whistles" to choose from.

AND just a few manufacturers make most of the brands.

AND these manufacturers all use many of the same internal components.

AND each HVAC equipment manufacturers GUARANTEES are materially the same.
